We use PKI technology for the digital content distribution in mobile environment. Encoding method is used TtipleDES and digital signature is used RSA. For the efficient methods and processes to the digital content distribution, we proposed the mechanism which consists of the sequential steps including the digital contents encoding step, rights management information signature step, and interconnection steps. As a result of this study, we propose the efficient and safe processes for the mobile content distribution environment.

As the rapid develoment of internet and information technology, the traditional library has been altered to the digital content service based on the world wide web. This paper proposes a design and implementation of an Artcle Union Catalog System(AUCS) based on metadata. The metadata set for the AUCS consists of twelve Dublin Core elements and one holdings element. The qualifiers of the proposed metadata elements are also represented. The AUCS system has an online cooperated cataloging system using the web interface or the 239.50 protocol, an union cataloging management system, and an integrated information retrieved system service. The integrated search and retrieval service of the AUCS displays not only the summary and detailed bibliographic information, but also the abstract, the table of contents, the digital content, and the copylfax service.

Contents Recommender System predicts user's preferences towards contents, and then recommends highly-predicted contents to user. Digital Identifier plays its part in identifying abstract works or digital contents in digital network environment. Digital Identifier could be effectively used in content-based filtering and collaborative filtering that are mainly used in Contents Recommender Systems. Therefore, this paper proposes an improvement of UCI metadata and resolution service for effective use of UCI in massive contents recommender systems. UCI metadata is expanded by adding elements such as abstract, keyword, genre, age, rate and review. Resolution service allows the operation systems to collect user preference for content by including input part of preference in a result page. This paper also designs and implements an improved UCI operation system and shows that the proposed improvement of UCI metadata and resolution service could be used for massive contents recommendation.

Previous studies on willingness to pay for digital content have mainly focused on audience factors and individual level. To complement the limitation of previous research, this study conducts a multilevel analysis to find the factors influence digital content purchases considering two axes: audience/media factors and individual/household levels. Using a sample of 10,172 individuals within 4,313 households, the analysis results show individual media factors including theater-going, experience with cloud services, and multi-screen service usage have the greatest effects on digital content purchases. At the household level, the media ownership factors that the number of laptops, wireless routers, and tablets have a greater influence than audience factors such as household size or household income. Our findings help scholars to enhance the understanding of individuals' media use considering household environmental factors and shed light on the importance of multi-screen service usage, and content providers to improve their digital content sales using multi-screen environment.

In this paper we present the combination of location based mobile advertisement services and dynamic digital signage markets has been developing recent days to provide consumer admired visual mobile advertisement on all kind transportation vehicles. In spite of that, the digital signage advertisement content management is still not that easy to manage the content dynamically as well operation is most time consuming to handle the contents dynamically in digital signage business. As location based services is most impactful service in shopping, the location responsive advertisement on vehicle signage will be most desirable mobile advertisement to help people migrate from one place to another place for travel or stay. This paper propose a mobile location responsive digital signage system for vehicles using the GPS and wireless infrastructure integrated with digital signage system. This proposed research use the centralized digital signage system architecture for the mobile advertisement application and this system can be expanded to different vehicles for digital advertisement including buses, trucks, train, air vehicle and any other form of mobile advertising vehicles. Also, this present an effective advertisement recommendation algorithm, by which the advertisement can be selected broadcasted for the right advertisement ventures more effectively as the service requested from advertiser. This paper present the emulated experimental result to evidence the proposed dynamic vehicle signage system performed better than compared with traditional signage random advertising. The emulated result proves that the advertisement recommendation algorithm can effectively works out the targeted key audiences in location responsive region the algorithm evaluated.

In recently, digital comic content distribution was not stable for illegal distribution and the weak of intellectual property right in the internet. The research activities of suggest the distribution model and secure intellectual property right are going in international standard communities, not yet in Korea. As the basis of the research, the general framework of international projects and standards such as MPEG-21, IMPREMATUR, FILIGRANE was analysed. Targeting on the domain of digital comics industry, the digital comics distribution structure and business flow model are defined adapting secured distribution system, DRM. The detail content of this research consist of three themes. The first, survey and analysis of the international standard ＆ leading DRM project's models. The second, suggestion of the service scenario on the digital comic content distribution. The third, suggestion of the model on the secured distribution of digital comics. Through this research targeting at the digital comics business, we found that standards technical items and requirements was well adapted into target domain, and would affect other domain in digital content industry.

The purpose of this study is to examine the effect of career plateau(structural and content plateau) on IT service technical engineers' career satisfaction and career withdrawal intention. Survey data were collected from 161 IT service technical engineers. The results indicated that structural and content plateau were negatively related to career satisfaction, and content plateau was positively related to career withdrawal intention, but not structural plateau. In addition, the results of hierarchical multiple regressions indicated that content plateau had stronger effect on career satisfaction and career withdrawal intention then content plateau.

The generated media by the general internet users, but self-produced content, provides video information only and has limitations. To satisfy internet users as consumers in the web 2.0 eras, it has needed to provide actual feeling contents that add various effects not just simple media. Therefore, this paper represents the existing media content with simple information based on the concept of ontology and the meaning to the subject for the media content. We will provide an actual feeling how to offer the configuration of a service model (AF-VS : Actual Feeling Video Service).
